Cao Yu who read the bible, is not a Christian, but can only be said as a playwright who full of enthusiasm about life. He always present something which are potential and rich poetry to the spectators. On top of this, Cao Yu allows the spectators to have a wide range of space to imagine and contemplate on his play. From what we saw and heard about the depraved sinners in "Lei Yu", we wonder there is God who take charge od this universe. Sinners desire to be redemned by GOd, repent from their sins and response to GOd's calling.
